I prayed with the Messenger of Allah ﷺ at Mina when the people were more numerous than they had ever been, and he led us in two units of prayer during the Farewell Pilgrimage.
حدثنا النفيلي حدثنا زهير حدثنا أبو إسحق حدثني حارثة بن وهب الخزاعي وكانت أمه تحت عمر فولدت له
صليت مع رسول الله ﷺ بمنى والناس أكثر ما كانوا فصلى بنا ركعتين في حجة الوداع
